Cook the rice in a large pan of boiling water for 12 minutes or until tender.
Cut the fish into large bite-size pieces.
Spray a nonstick wok or large frying pan with oil and heat, add the curry paste and stirfry over medium heat for 1 minute.
Stir in the pasta sauce and water and bring to the boil.
Add the fish pieces (and vegetables if desired), reduce the heat slightly and simmer for about 5 minutes or until the fish is cooked (test by flaking the flesh with a fork).
Push the fish to one side of the pan and stir the yogurt and coriander into the sauce, then gently stir in the fish to coat. (Stirring the fish too much could cause it to fall apart.) Don't let the sauce boil again after adding the yogurt.
Serve with long-grain or basmati rice.
